Thiophenol → Ethyl 2-phenylsulfanyl-thiazole-5-carboxylate

Participants

Reaction Steps

A suspension of 2-bromo-1,3-thiazole-5-carboxylic acid ethyl ester (1.5 g, 6.15 mmol, 1 eq) and K2CO3 (1.7 g, 12.3 mmol, 2 eq) in EtOH (60 mL) is cooled in an ice bath, and thiophenol (0.631 mL, 6.15 mmol, 1 eq) is added. The reaction is monitored by HPLC until the starting material is consumed. The reaction mixture is filtered (to remove a solid by-product), and the solvent is removed in vacuo. The crude mixture is purified by silica gel chromatography using a Biotage Flash 40S column using 2% EtOAc in hexanes to afford the product as an oil (0.784 g, 46%). MS (ESI) for C12H11NO2S2m/z 266.1 (M+H)+.
